Worked on the web-platform-tests/wpt-metadata repository to improve the accuracy and maintainability of CSS test metadata. Focused on metadata management and testing, the work involved cleaning up and consolidating entries in META.yml using YAML, specifically by removing a reverted test entry linked to a Bugzilla issue and finalizing the status of CSS border tests. This approach reduced misclassifications and improved continuous integration stability by aligning metadata with project standards. The changes supported faster test discovery and ongoing maintenance, demonstrating attention to detail in metadata consistency and a methodical approach to stabilizing test definitions within the broader testing infrastructure.
